That is more-or-less the impression I've always had; however I've
recently read a couple of period articles which make me think that
greater emphasis than is generally thought was placed on kudzu's value
as a forage crop. A masters thesis at Auburn, "A study of the effect
of various treatments on the rooting and survival of kudzu seedlings
and vine cuttings" (ca. 1941) had this introductory paragraph:
"Kudzu (Pueralia thumbergiana) is a plant which most agronomy
workers agree is well adapted as a perennial hay crop for the
Southern States. Kudzu does well on land that is too steep
or too low in fertility to support other hay crops. This is
especially true in the Piedmont region of the southeastern
states where steep slopes accompanied by a humid climate have
resulted in untold losses through erosion on farm lands in
this area."
More illustrative is a circular published (1939, and earlier) by the
Agricultural Experiment Station of the Alabama Polytechnic Institute
titled "Kudzu Its Value and Use in Alabama":
"Kudzu, a perennial legume that produces large yields of hay,
is adapted to temporary grazing by livestock, is an excellent
soiling crop and is sufficiently drout-resistant to produce
good yields when other crops fail. Its feeding value compares
favorably with other legumes. It is valuable for soil building,
stoping erosion, and planting on road banks, fills, and along
gullies..."
The remainder of the 20 pages are spent extolling (citing experimental
data) the many virtues of kudzu. The Hay Crop section gets 4 pages;
Grazing Crop, 6 pages; Soil Improvement, 2 pages; Propagation, 3 pages;
Erosion, 1 page; Care(!), 2 pages; summary, 1 page. Just before the
Summary, there is a cautionary section:
"Kudzu as a Pest"
"Some farmers have opinions that kudzu may become a pest,
may not be eradicated, and may spread where it is not wanted.
Such ideas are unfounded. It may be easily eradicated by
grazing or by plowing. Kudzu has been confined to the edges
of fields at Auburn for a period of 35 years and has never
become a pest or spread to areas where it was not wanted.
It may be confined indefinitely to terrace ridges in
a field simply by cultivating the field in row crops."
Read today, much of the circular seems a delicious satire - there are
cautions on how to avoid the loss of kudzu seedlings, warnings to not
allow livestock to overgraze, etc. The data shown in the report really
*is* impressive; I imagine that in its time kudzu seemed as much The Answer
as, in their times, . Rec.gardens
added to distribution, better historians may wish to add corrections.
